1 cup powdered milk
1/2 cup baking soda OR 1/2 cup cornstarch (I prefer the cornstarch)
6-8 drops of essential oil of your choice for fragrance
4-6 drops food coloring
In blender or food processor, stir together milk and soda or cornstarch. You may add coloring at this time 1-2 drops at a time so you can see how the color will develop. Blend in essential oil. Store in NONPLASTIC container for several days to allow fragrance to develop. (If you store it in plastic container the fragrance will be absorbed by the plastic)
Use 1/2 cup per bath.
